Examples of java.io.DataInputStream.readInt()

java.io.DataInputStream.readInt()
See the general contract of the readInt method of DataInput.
Bytes for this operation are read from the contained input stream. @return the next four bytes of this input stream, interpreted as anint. @exception EOFException if this input stream reaches the end beforereading four bytes. @exception IOException the stream has been closed and the containedinput stream does not support reading after close, or another I/O error occurs. @see java.io.FilterInputStream#in
